Cassiodorus

Few men are controlled by reason, and few are pleased by a right purpose. The mob, rather, is led to what was plainly invented for oblivion of its cares. For it supposes that whatever serves its pleasure must also be linked to the happiness of the age. Therefore, let us grant the expenses, and not be forever giving from rational considerations. Sometimes it is useful to play the fool, and so control the joys the people long for.
